Antje the walrus was the NDR mascot for decades. When the living one was discarded, it was replaced by a new Antje drawn by Janosch, who was later given her own series in which she has adventures with the little tiger and the little bear. The fish Schlüter, who speaks in Viennese dialect and was actually supposed to serve as her provisions, is always with her in a red plastic bucket, even when she is in the country. Excitement in the early hours of the morning! Schlüter jumps out of the river in front of the house and thinks he has been frightened by a sea monster! But there is no monster to be seen for miles around. Antje grabs "Grandpa Pushkin's Diary" and finds an old photo of the Loch Ness monster. And our four friends find themselves back in Scotland. Will they be able to solve the mystery of Loch Ness?
